COYOLXAUHQUI One of the daughters of Coatlicue, she disapproved of the plans of the other offspring of the Aztec earth goddess to kill their mother, and rushed to warn her. Unfortunately, she was met by the newborn and fully-armed Huitzilopochtli,who killed her, going on to wreak carnage among the other sons and daughters of Coatlicue. When the fight was over, Huitzilopochtli's mother told him of his sister's goodness, and the god cut off Coyolxauhqui's head, throwing it up to the sky, where it became the moon.
